Which three features are unique to the large intestine?

1. The teniae coli are three bands of smooth muscle forming the longitudinal muscle layer of the colon. 2. Their tonic contraction bunches the colon into pouches called haustra, giving it a wrinkled look. 3. Small fat-filled sacs of visceral peritoneum attached to the teniae coli are the epiploic appendages. 4. Those three together are unique to the large intestine, so the last option is correct. 5. Villi, microvilli and circular folds are absent from the large intestine and belong to the small intestine. 6. Rugae and gastric pits belong to the stomach, so the second option names the wrong organ. 7. Peyer's patches and lacteals are concentrated in the small intestine, especially the distal ileum. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 23 "The Digestive System", section 23.5 The Small and Large Intestines_
